Abstract :
Low-cost, rapid and reliable detection technologies for soil nutrients can improve the effectiveness of data collection for site-specific management of soil fertility. In this study, an automated fluidic control system was developed for rapid detection of soil nutrients. Micro pump and valves, controlled by a lap-top computer, delivered a sequence of test solutions to a test chamber where ion selective electrodes are mounted. A 90 seconds test time with acceptable accuracy was demonstrated. This automated soil nutrient fluidic system can further be miniaturized and may be useful for in-field rapid detection of soil nutrients.
